x86/fpu/math-emu: Fix function cast warning
Building with 'make W=1', gcc points out that casting between
incompatible function types can be dangerous:
arch/x86/math-emu/fpu_trig.c:1638:60: error: cast between incompatible function types from ‘int (*)(FPU_REG *, u_char)’ {aka ‘int (*)(struct fpu__reg *, unsigned char)’} to ‘void (*)(FPU_REG *, u_char)’ {aka ‘void (*)(struct fpu__reg *, unsigned char)’} [-Werror=cast-function-type]
1638 | fprem, fyl2xp1, fsqrt_, fsincos, frndint_, fscale, (FUNC_ST0) fsin, fcos
| ^
This one seems harmless, but it is easy enough to work around it by
adding an intermediate function that adjusts the return type.
